Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Glasflugel--Ing. E. Hanle (Glasflugel) Model GLASFLUGEL Kestrel sailplanes. This proposed AD would require you to inspect the airbrake actuating shaft for deformation and cracks (hereon referred to as damage). If any damage is found, this proposed AD would also require you to repair or replace the airbrake actuation shaft. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. We are issuing this proposed AD to detect and correct damage to the airbrake actuation shaft, which could result in failure of the airbrake control. This failure could lead to loss of control of the sailplane.
